:This inventionlrelatesvto heddle bar locking
structures for use-in retaining heddle bars in
heddle frames.

A still further object
is the provision of heddle bar locking elements
which may be removed or replaced without the
removal or dismemberment of the other members

provision of heddle frame‘harness ends possess
of my invention, which permit the heddle bars to
be securely held against movement relative to
the harness ends 4.
The locking structures of my invention consist
of a combination of a lock pin I I and a securing

Having thus described my invention, what I
claim is:
1. A heddle bar locking structure comprising a
pin adapted to movably extend through the end
opening in a heddle bar, said pin being provided
with an aperture in one end thereof, and an ele

of said bar-end openings comprising a spring wire
element including a substantially straight portion
adapted to extend through the aperture in the

mount the heddle bars on the harness ends, a pin
inserted through openings in the ends of said
heddle bars securing the heddle bars against
movement, and a wire spring element extending
through an aperture in the end of said pin secur
ing said pin from movement out of said bar open
ings, said Wire element being fastened at one end
to said harness end and releasably engaged at
the opposite end to said harness end by an angled
portion including a hooked end.
4. A heddle bar locking structure comprising
